How to accurately distinguish the quality of coffee beans

Coffee is one of the most popular drinks in the world, and the quality of coffee beans directly affects the taste and flavor of coffee. For coffee lovers, it is very important to know how to accurately distinguish the quality and advantages of coffee beans.

First of all, observing the appearance is the first step to judge the quality of coffee beans. Good coffee beans are usually shiny, uniform in color and complete in shape. If there is oil on the surface or the color is uneven, it may mean that the beans have been over-roasted or stored for too long. In addition, you also need to pay attention to defects such as cracks or deformation.

Secondly, smelling is also an important part of evaluating the quality of coffee beans. Good coffee should have a strong and attractive aroma. The strong fragrance can be smelled soon after fresh roasting and lasts for a long time; while low-quality or severely aged beans are difficult to emit a pleasant and refreshing feeling.

Finally, tasting in terms of taste is the key to judging the quality of coffee beans. Good coffee should have a mellow and balanced taste, not too bitter or too sour. In addition, the quality of coffee can be judged by observing whether there is a noticeable aftertaste. High-quality coffee usually leaves a long-lasting and pleasant aftertaste in the mouth.
